Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a rear rotary shaft mounting structure for a two-shaft rotary device.

(B) Conventional technology Conventionally, in a two-shaft rotary device, a rear rotary portion is arranged behind the front rotary portion, and the front and rear rotary portions are interlocked with each other via an interlocking case. Has one end pivotally supported by the side cover and is interlockingly connected to the rear end of the interlocking case.

(C) Problems to be solved by the invention However, since the shaft support part of the rear rotary shaft and the interlocking connection part with the interlocking case are located in a projecting shape from the inner and outer surfaces of the side cover, respectively, On the outside of the cover, there is a problem that straw, grass or the like is caught, and on the inside of the cover, the rotary claw cannot be attached.

In addition, it is difficult to attach the rear rotary shaft.

(D) Means for Solving the Problems In the present invention, therefore, the rear rotary portion is disposed behind the front rotary portion, and the front-rear rotary mechanism is provided via the interlocking mechanism disposed in the tillage transmission case and the interlocking case. In a two-axis rotary device in which parts are interlockingly connected, the interlocking case is
Arranged along one side cover of the rear rotary cover,
At the rear end of the interlocking case, the rear end of the output shaft arranged in the interlocking case is interlockingly connected to one end of the input short shaft arranged in the rear rotary cover, and the other end of the input short shaft is inward. An input short shaft is connected by concentrically and detachably connecting a tubular body having a flange portion at the extended end portion and the flange portion fixed to one end of the main body long axis. And the main body long shaft constitute a rear rotary shaft, the other end of the main body long shaft is detachably supported by a shaft support plate connected to the rotary frame, and the outer peripheral surface and the flange portion of the main body long shaft are supported. A plurality of rear rotary pawls are attached to the outer peripheral surface of the cylindrical body at intervals in the axial direction, and further, a concave portion is formed in a portion of the one side cover located around one end of the input short shaft, After being closest to the one side cover (13), put the rotary claws in the overlapped state around the recessed part. It is intended to provide a rear rotary shaft mounting structure having a biaxial rotary structure characterized by being rotatable.

(E) Action When performing cultivating work, the power from the front rotary part is transmitted to the rear rotary shaft of the rear rotary part, which is arranged behind the front rotary part, through the interlocking mechanism arranged in the interlocking case. hand,
The soil that has been cultivated and scattered rearward at the front rotary part can be further cultivated at the rear rotary part to maintain the required fine soil property. The input short shaft to be connected and the main body long shaft are detachably connected, and the other end of the main body long shaft is detachably supported by a shaft support plate connected to the rotary frame. The main shaft of the main body can be quickly and easily removed from the input short shaft and the shaft support plate when the claws are replaced and the input short shaft is extended inward. In addition, the rotary claw can be attached to the outer circumference of the short shaft, so that the plowing width can be formed as wide as possible.

(F) Effect According to the present invention, a large number of rotary pawls can be attached while simplifying the structure, the rotary shaft can be easily attached and detached, and all the problems that have been conventionally problematic can be solved. effective.

Further, since the cylindrical body having the flange portion is detachably attached to the input short shaft, the work of attaching and detaching the main body long shaft to which the rear rotary claw is attached and the cylindrical body can be performed very easily.

Further, since the rear rotary pawl is arranged so as to approach the one side cover, it is possible to eliminate residual tillage.

Furthermore, since the recessed portion is formed in the portion of the left side cover located around one end of the input short shaft, the amount of protrusion of the one side cover to the outside is small, and it is possible to prevent wrapping of straw.
